Filed: 1991-11-26
Abstract: PURPOSE:To permit the sure information about collision during the active diagnosis of an accelerating speed sensor by interrupting diagnosis when the second accelerating speed sensor for detecting the decelerating speed of a vehicle which is lower than that at collision operates. CONSTITUTION:If the second accelerating speed sensor 6 operates during the diagnosis for a system constituted of the first accelerating speed sensor 1, collision detecting means 2, starting means 3, and a diagnosing means 5, the means 5 interrupts diagnosis. Accordingly, if a starting signal at an L level is inputted into a terminal P1 from the means 2, a transistor T1 is turned OFF, and a transistor T2 is turned ON. Since, at this time point, the sensor 6 is turned ON at the decelerating speed lower than that at collision, electric current flows into an ignition source S1 from an electric power source V1, and occupant protecting device 4 operates. Each voltage at B point, A point is applied as the + or - input of a comparator CP, and the voltage at the A point in the case when the sensor 6 is turned ON becomes less than that at the B point, and the output terminal P2 of the CP becomes H level. The means 5 reads out the state of the sensor 6 from the terminal P2, and interrupts the diagnosis for the system.
